12 paź 2023 · When a radiologist describes a region as “FDG avid” in the context of a PET scan, it means that this specific area has absorbed a notable amount of FDG. In most cases, this points towards increased metabolic activity, which can be a sign of various conditions, including cancer.
18 paź 2016 · In malignancies which are known or expected to have high FDG uptake, we advise caution in reporting incidental findings on CT that are not FDG-avid as suspicious or malignant. Furthermore, equivocal abnormalities by CT criteria alone (e.g. an ovarian cyst) that would ordinarily mandate further investigation, may be characterised by the absence ...
30 mar 2023 · While there is a mild reduction in size and FDG avidity of the right inguinal lymph node (dashed arrow), no significant change is noted in the overall disease, including the largest and most avid lesion in the right lung (blue arrow) and the other lung nodules (solid black arrow).
9 paź 2024 · Due to the dense breast tissue (a), no suspicious lesions were detected on mammography. Ultrasonography of the right breast measured a 1.5 cm lesion (b). Given the patient’s young age (aged 30) and clinical suspicion of metastases, FDG-PET/CT was performed (c–e).
1 maj 2007 · Learning Objectives: 1. Describe tumors likely to show low FDG avidity. 2. Identify reasons for low FDG uptake in known malignancies. 3. Understand the importance of including low FDG uptake tumors in differential diagnosis.
1 paź 2013 · Common and uncommon benign FDG-avid lesions that result from surgery and surgical procedures, radiation therapy effects and complications, and chemotherapy effects and complications are reviewed, with emphasis on distinguishing them from residual or recurrent cancer.
17 cze 2020 · D5PS score of 1 shows no FDG avid lymph nodes (LNs) or other lymphoma-related lesions. D5PS score of 2 shows right level II LNs with uptake above background, but not exceeding MBP. D5PS score of 3 shows same right-sided LNs with mildly increased FDG avidity, between MBP and liver.
